FNC 28
DXOR
• While the command input is OFF, the data of the transfer destination [
• While the command input is ON, the data of the transfer source [
change.
• When a constant (K) is specified in the transfer source [
converted into binary format.
• The exclusive logical sum operation is executed in units of bit as shown in the table below (1 ∀ 1 = 0, 0 ∀ 0 = 0,
1 ∀ 0 = 1, 0 ∀ 1 = 1).
Logical operation
(unit: bit)
Program example
By combining WXOR and CML (FNC 14) instructions, the exclusive logical sum not (XORNOT) operation can be
executed.
